Stackable roll containers

ABSTRACT

The invention concerns a stackable roll container  1 , in particular, for the transporting of foods, cosmetic articles, or items of practical use in large bundles, with a preferably rectangular bottom  2 , on which transport rollers  3  on the underside and two attachment walls  4, 5  opposite one another are located, wherein each of the attachment walls  4, 5  opposite one another has a retracted, rear, vertical end brace  7, 8 , opposite a vertical base plane E-E, and a lower, horizontal base brace  10, 11  adjoining it.

The invention refers to a stackable roll container, in particular for the transporting of foods, cosmetic articles, or items of practical use in large bundles with a preferably rectangular bottom, on which transporting rollers on the underside and two attachable walls that are opposite one another are located.

Also, three-side solutions are the subject of the invention, wherein a third wall can be provided as a back wall. Also, containers closed on all sides are basically conceivable (see below).

For the transport of foods, cosmetic articles, or other items of practical use, so-called roll containers are predominantly used by distribution channels. A distinction is hereby made between so-called roll containers that cannot “nest” in one another—that is, roll containers that cannot be stuck into one another—and stackable roll containers. Roll containers that cannot nest in one another require considerable storage room costs and are impractical in handling. Also the dismantling expense (for example, for return transport) is considerable, and the damage rate to rollers, frames is particularly large, in particular with containers transported overhead.

Roll containers that can nest in one another have a specially designed bottom frame, for example, in a trapezoid form of the bottom construction or the form of a “Z” or a “V,” wherein these known constructions make possible a straight-line or lateral nesting.

The different embodiments of the roll containers that can nest in one another are, in part, weight-heavy constructions, have a loud noise emission, and are not suited or have only a limited suitability for modern conveying technology.

The goal of the invention under consideration is, in contrast to this, to create a stackable roll container of the type mentioned in the beginning, which, with a simple structure does not require dismantling, makes possible a space-saving storage of unneeded roll containers in the branch or in the distribution warehouse and in the truck, and does not require any high tools costs for re-equipping.

In accordance with the invention, this goal is attained in that each of the attachment walls opposite one another has a retracted, rear, vertical end brace opposite a vertical base plane, and an adjoining lower, horizontal base brace.

By means of this special construction design, a roll container that can nest into another is created, and is able to fulfill all the requirements that may appear in actual practice and, at the same time, can be produced in a simple manner.

In another development of the invention, each attachment wall has an upper, horizontal base brace in the base plane, and adjoining this a front, vertical end brace. The retracted, rear, vertical end brace and the horizontal, upper base brace, on the one hand, and the lower, horizontal base brace and the front, vertical end brace, on the other hand, are connected to one another via retracted areas. By means of these retracted areas, it is possible to stick the roll containers into one another in a simple manner.

With containers with vertical and horizontal lattice bars of the attachment walls, the horizontal lattice rods of the opposite attachment walls in the retracted area opposite the base plane, can be connected to the front and rear end braces. The vertical lattice bars can be in the area of the base plane and can be connected to the individual, upper, horizontal base brace and, by means of inclined connections, to the individual, lower, horizontal base brace.

In another configuration of the invention, each bottom can have at least one recess for locking, in the area of the transport roller lying above it, of the roll container stacked above it, whereby a secure stacking capacity of the roll containers arranged one above the other is attained. Moreover, the possibility exists that in another configuration of the invention, each bottom, on the upper side, has at least one groove for guiding at least one of the transport rollers. One has to preferably take care that the guiding of the roller is as free of jerking as possible, so that a container can be inserted or thrust effortlessly and easily into the bottom frame (or the running groove) of a container found beneath it.

In another configuration of the invention, a closure insertion wall—transverse to the two attachment walls opposite one another—can be located between them, wherein the closure insertion wall and the two attachment walls can be affixed to one another and to the bottom. All side walls can be affixed to the bottom by means of plug connections in recesses, which are known. In accordance with the invention, the side walls, when inserted, can deflect laterally within the desired tolerances, so as to facilitate the nesting. In a manner different from rigid containers from the state of the art, this mobility permits the slight pressing apart of the side walls, in order to be able to push the containers more easily into one another.

If a three-side solution with a rear wall is provided, then this rear wall can preferably be connected to the side walls via suitable hinges. The hinges thereby likewise permit the aforementioned movement of the side walls within the desired tolerance for an easier nesting. The hinges preferably permit a clearance of 30 mm-40 mm, perhaps by means of a longitudinal hole construction or with other hinge displacement elements.

Finally, the container, in accordance with the invention, can also be provided with a (preferably suspendable or metal) door, in order to close it from the front. Alternatively, another suitable front cover (tarpaulin, etc.) can also be used to close the container.

Preferably, intermediate bottoms are provided, which can be laid or suspended between the side walls and are used for load distribution or stabilization of the container. If a rear wall is provided as a third side wall, the intermediate bottoms can also contribute to the stabilizing connection of the walls among one another, if they interact mechanically with each wall in a suitable manner (suspended on three sides; suspended on two sides with a stop on the third wall, etc.).

The invention will be explained below in more detail with the aid of exemplified embodiments shown in the drawing. The figures in the drawing show the following:

As shown in FIGS. 1 and 5-7, the invention concerns a stackable roll container 1, which can be used, in particular, for the transporting of foods, cosmetic articles or other items of practical use in large bundles. This roll container 1 preferably has a rectangular bottom 2, on which in accordance with FIG. 1 transport rollers 3 on the underside and two attachment walls 4, 5, opposite one another are located. These attachment walls 4, 5 can be inserted into corresponding recesses of the bottom 2 by means of pins 40, 41, and 42, 43, in accordance with FIGS. 1 and 5.

In accordance with the invention, each of the attachment walls 4, 5 opposite one another has a retracted, rear, vertical end brace 7 or 8 opposite a vertical base plane E-E in accordance with FIG. 7, and a lower, horizontal base brace 10, 11, which adjoins said brace via an incline 50 or 51.

Moreover, each attachment wall 4, 5 has an upper, horizontal base brace 13, 14 in the base plane E-E in accordance with FIGS. 1 and 6, and adjoining it, a front, vertical end brace 17, 18.

From FIG. 1, one can see that the retracted, rear, vertical end brace 7, 8 and the horizontal, upper base brace 13, 14 of each attachment wall are connected to one another via a retracted area 20, 21. Likewise, the horizontal, upper base braces 13, 14 [sic; lower base braces 10, 11] and the front, vertical end braces 17, 18 are connected to one another via retracted areas 23 and 24, in accordance with FIG. 1 or in accordance with FIGS. 5 and 6.

The attachable side walls 4, 5 can be provided with horizontal lattice braces 26 and 29 and with vertical lattice braces 29 and 30. In accordance with the invention, the horizontal lattice braces 26 and 29 of the opposite attachment walls 4, 5 are connected to the front and rear end braces 7, 17 or 8, 18 in the retracted area opposite the base plane E-E. The vertical lattice rods 27 and 30 are hereby in the area of the base plane E-E and are connected to the individual upper, horizontal base brace 13, 14 and to the individual lower, horizontal base brace 10, 11 via inclined connections 32 and 33 (see FIG. 6).

In order to hold the roll containers in accordance with the invention in their shoved-in position, depicted stacked in FIGS. 2, 3, and 4, there is the possibility in accordance with the invention that each bottom 2 has at least one recess 35 in accordance with FIG. 1 for the locking, in the area of the transport roller 3 lying above, of the roll container stacked above it. Moreover, each bottom 2 has on the upper side at least one groove, which is not depicted in more detail, for guiding at least one of the transport rollers 3 of the roll container 1 stacked above it.

Bottom 2 preferably is made of plastic and has recesses so that the attachable side walls 4 and 5 can be affixed on the bottom via plug connections, which are not depicted in more detail.

With the embodiment in accordance with FIGS. 2-4, the stackable roll container has two attachable walls 4, 5 opposite one another, which have a special constructive design for nesting feasibility.

According to the invention as per FIGS. 8-11, there is also a possibility for the roll container 1′ to have a closure insertion wall 37 between the two attachable walls 4 and 5 opposite one another, which are [sic; is] connected both to the individual attachable walls 4 and 5 as well as to bottom 2 via connections that are known.

With this construction in accordance with the invention, the attachable walls 4 and 5 also have the configuration according to the invention, as they are depicted in particular in FIGS. 1 and 5-7 in detail, for a right attachable wall. The closure insertion wall 38 is not affected by it, so that there is the possibility according to FIGS. 9-11, of also transporting this construction form of the attachable roll container in a stackable form in a space-saving manner.
